Part alignment and zero point workholding

This is way more of a theoretical/fun question rather than real world practical, but here goes... 

 

I'm using a 4th-axis rotary equipped with a triangular zero-point tombstone.  It's modelled in CAD, with WCS set to the center of rotation/platter face.  

 

Theoretically, if master gauging pallets (w/precision ground bore/sides) were mounted to each face, could Fusion's Part Alignment features be used to calculate deviation and potentially improve accuracy in future machining operations?

Part alignment would maybe work but its is on a per part basis, so you would have to run it in each new instance of your work holding setup.

 

I have done something similar with a Lang Adaptor I made.

I probed the Gauging pallet in the machine and noted the deviations from theoretical and Adjusted the Joint Origin that attached the Work holding to the Adaptor/Tombstone.

 

Now that its calibrated in my parts come out perfect and its a one off thing.

 

You would have to do this 3 times for your tombstone

I would never have thought about using Joint Origin.... A truly elegant solution.  Thank you, Sir!
